[译] 对一种疾病免疫不一定使人对另一种疾病免疫。
[误] The immunity to one disease does not necessarily cause a person to be immune for another.

[正] The immunity to one disease does not necessarily cause a person to be immune to another.
[注] 形容词 immune (n. immunity) 之后须用介词 to，表示“对……免疫”，又如：A person who suffered from measles will be immune to it. 患过麻疹的人对麻疹免疫。
